We've had voice input and voice output with computers for a long time, but it's never felt like spoken conversation. At best it's a series of separate voice notes. It feels more like texting than talking. These demos show people talking to artificial intelligence. This is new. Humans are more partial to talking than writing. When people talk to each other (in person or over low-latency audio) there's a rich metadata…

I started using the Pi LLM app (by Inflection.ai) with my kids about six months ago and was completely blown away by how human-like it sounded, not just the voice itself but the way it expresses itself, the tiny pauses and hesitations, the human-like imperfections. It does feel like conversing with another human -- I've never seen another LLM do that. (We mostly use it in car trips -- great for keeping the kids (ages…

This is great, thanks for sharing. Yeah the little imperfections work really well, it's the most humanlike computer voice I've heard so far.

How does the interruption of the AI by the user work? Does GPT-4o listen all the time? But then how does it distinguish its own voice from the users voice? Is it self-aware?

One of the techniques for a voice assistant to distinguish its own voice from background sound is called a Fourier transform, although I expect that the state of the art in this area also includes some other techniques and research.

If you've used one, you might know that you can easily talk to a smart speaker even when it is playing very loud music, it's the same idea.

This video explains more quite well: https://www.youtube.com/watch?v=spUNpyF58BY

That woman's voice intonation is just scary .Not because it talks really well, but because it is always happy, optimistic, enthusiastic. And this echoes to what several of my employers idealized as a good employee. That's terrifying because those AI become what their master's think an engaging human should be. It's quite close to Bostondynamics di some years ago. what did they show ? You can hit a robot very hard whi…

I see a wider problem here, interacting with this AI could train people to behave the same way with real people. Interrupt them whenever you feel like it, order them to do things, turn them off, walk away while they are still talking. People may start imitating the AI's behavior to put someone down, treat them as second class, as though they were also an AI just to be used, and not a person. If people use this conversational AI often then the ways they interact with it will creep into peoples use of language with each other. People imitate each other all the time, they will start imitating the AI. They'll think it is funny but after a while it may not turn out to be so funny.

This is a very cool demo - if you dig deeper there’s a clip of them having a “blind” AI talk to another AI with live camera input to ask it to explain what it’s seeing. Then they, together, sing a song about what they’re looking at, alternating each line, and rhyming with one another . Given all of the isolated capabilities of AI, this isn’t particularly surprising, but seeing it all work together in real time is pre…

My new PC arrives tomorrow. Once I source myself two RTX 3060's I'll be an AI owner, no longer dependant on cloud APIs. Currently the bottleneck is Agents. If you want a large language model to actually do anything you need an Agent. Agents so far need a human in the loop to keep them sane. Until that problem is solved most human jobs are still safe.

You are far better off investing in one or more 3090s and loading up on DDR RAM.

Very interesting and extremely impressive! I tried using the voice chat in their app previously and was disappointed. The big UX problem was that it didn't try to understand when I had finished speaking. English is a second language and I paused a bit too long thinking of a word and it just started responding to my obviously half spoken sentence. Trying again it just became stressful as I had to rush my words out to…

FYI: In the current voice chat available in their app, if you press and hold the white circle, it will listen for you until you lift your finger. This pretty much fixed my issues with it!

That they are offering more features for free concurs with my theory that, just like search, state of the art AI will soon be "free", in exchange for personal information/ads.

People are directly asking for suggestion/recommendations on products or places. They'll more than recoup the costs by selling top rank on those questions.

I have some questions/curiosities from a technical implementation perspective that I wonder if someone more in the know about ML, LLMs, and AI than I would be able to answer. Obviously there's a reason in dropping the price of gpt-4o but not gpt-4t. Yes, the new tokenizer has improvements for non-English tokens, but that can't be the bulk of the reason why 4t is more expensive than 4o. Given the multi-model training…

GPT-4o is multi-modal but probably fully dense like GPT-2, unlike GPT-4t which is semi-sparse like GPT-3. Which would imply GPT-4o has fewer layers to achieve the same number of parameters and same amount of transformations.

The most impressive part is that the voice uses the right feelings and tonal language during the presentation. I'm not sure how much of that was that they had tested this over and over, but it is really hard to get that right so if they didn't fake it in some way I'd say that is revolutionary.

(I work at OpenAI.) It's really how it works.
